(a) What changes occurs when AgCl is doped with CdCl2?
(b) What type of semiconductor is produced when silicon is doped with boron?
(a) Impurity defect of ionic solids is produced when AgCl is doped with CdCl2. Due to this defect vacancies are created that result in higher electrical conductivity of the solid.
(b) p-type semi-conductor is obtained when silicon is doped with boron.
